ONE-PIECE REEL ARM AND AN END FRAME FOR PILE FABRIC REEL This invention relates to a one-piece reel arm and an end frame for a pile fabric reel. More particularly, this invention relates to a flat one-piece reel am from which an end frame of a reel for pile fabrics is shaped. Still more particularly, this invention relates to a reel formed from flat one-piece reel arms for winding of pile fabric in spaced convolutions to prevent damage to the pile or surface of the fabric during storage and transportation In transporting pile fabrics such as velvet and plush in layered conditions, it has usually been necessary to maintain the layers of the fabric at some spacing relative to each other in order to avoid crushing or other damage to the pile fabric. Accordingly, various types of frames generally referred to as reels have been used to transport pile fabrics in a manner so as to avoid damage. These reels have generally been made of a pair of spaced end frames and a spacer means between the end frames which is of a length substantially equal to the width of Y fabric being wound for holding the end frames apart. The end frames, in some instances, have been formed with outwardly diverging arms each of which is provided with an equal number of spaced impaling hooks for engaging with the ends of a pile fabric to secure the fabric in a layered condition on the reel. In other instances, the end frames have been made in a generally hourglass configuration and have had separate hook plates secured on the arms of the end frames along radial planes for impaling the fabric on the reels. The hook plates have also sometimes utilized pivotally mounted hooks and mechanisms for pivoting the hooks between various positions of use.

These heretofore used reels and reel arms, however, have had several disadvantages. For example, in those instances above where the reel arms have been of the outwardly diverging type, the end frames have become bent or warped during transportation due to the weight of the fabric wound on the frames and the vibratory torsional loading of the end frames. Also, while the reels of the latter type mentioned above overcome these disadvantages to a degree by being formed by one or more one-piece members of thickened cross section for increased bending strength, these reels have required separate hook plates to be secured, as by riveting, to the radiating arms of the members because the arms have been too thick to knock out the necessary hooks. Further, these frames have not only not solved the problem of bending in transit when loaded but have also been of such weight as to be prohibitively expensive to ship in quantity to a fabric shipper.

Further, the end frames of heretofore used reels have in some cases been mounted on the spacer means in an adjustable manner for movement relative to each other so as to take up any slack in the wound fabric. However, during use, especially in transporting the reels with the wound fabric, the end frames have become skewed on the spacer means. This has sometimes resulted in a falling away of the fabric from the impaling hooks so that, upon arrival at a destination, the fabric has been completely separated from one of the end frames with consequent damage to the fabric.

Additionally, many of the reels have been made with sharp edges which have caused injury to the personnel handling the reels as well as to the fabrics when the fabrics which have fallen from the end frames have been subsequently removed from the remainder of the reel.

Briefly, the invention provides a one-piece reel arm and an end frame constructed of a pair of such reel arms. The reel arm is initially formed in an integral manner as a flat strip with a raised rib extending longitudinally of the strip, a pair of spaced sections which contain impaling hooks, an uninterrupted intermediate section between the hook-containing sections, and ends which are slightly inclined in the direction of the raised rib portion and which contain at least one aperture iii'fjthe rib for facilitating securement to a spacer bar. In order to construct an end frame, a pair of one-piece reel arms are bent about lines passing between each of the hook-containing sections and the intermediate section in a direction opposite to the raised rib portion into a substantially triangular shape. Thereafter, the ends of the bent reel arms are placed over each other in a lapped manner and a clamp means is mounted over the lapped ends to maintain the relative positions of the reel arms. In addition to maintaining the reel arms in a fixed position, the clamp means also form a socket for receiving one end of a spacer bar of acompleted reel. Thus, after a pair of end frames are formed, the ends of a single spacer bar can be inserted into each socket to form a completed reel which is then in a state to accept a length of pile fabrics.

The clamp means of the invention includes a pair of elongated clamps and a securing means for holding the clamps together. Each clamp is sized so as to extend over the overlapped ends of the bent reel arms as well as to project past the reel arms in order to define the socket for the spacer bar. In one embodiment, the securing means is made adjustable in order to permit a loosening of the clamps and a removal of a mounted spacer bar. In another embodiment, the securing means is of a permanent type, such as a rivet, so that the end frames are of a substantially permanent construction. In either embodiment the sockets defined by the clamps are of a depth to permit the spacer bar to be received in a more or less adjustable manner so as to permit the spacing between the end frames of the reel to be adjusted. This allows a slight tension to be imparted in a mounted fabric so as to avoid skewing of the end frames during use.

The reel arms of the end frames are also formed with lightening holes along the various sections in order to reduce the weight of the reel arms. This is of especial importance in shipping of a large quantity of reel arms while in a flattened state since a substantial weight reduction can be effected.

The reel arm of the invention is further formed with rounded comers and edges on the exposed parts in order to avoid injury to the personnel handling the reel arm or reel.

Accordingly, it is an object of the invention to provide a one-piece reel arm having integral hooks for a pile fabric reel.

It is another object of the invention to provide a one-piece flat strip reel arm for a pile fabric reel.

It is another object of the invention to provide a one-piece flat strip reel arm which is nestable for shipment.

It is another object of the invention to provide a lightweight stable one-piece reel arm for a pile fabric reel.

It is another object of the invention to provide a pile fabric reel which is stable against bending and twisting.

It is another object of the invention to provide a pile fabric reel with end frames which are adjustably spaced from each other to impart tension in a fabric mounted thereon without skewing of the end frames during use.

These and other objects and advantages of the invention will become more apparent from the following detailed description and appended claims taken in conjunction with the accompanying drawings in which:

FIG. 8 illustrates a view taken on line 8-8 of FIG. 1; and

FIG. 9 illustrates a view of a one-piece reel arm of the invention bent into a triangular shape for incorporation into an end frame.

Referring to FIG. 1, a reel 10 is formed by a pair of spaced end frames 11 and a spacer bar 12 mounted at the ends within the end frames 11. The end frames 11 are spaced apart by the spacer bar 12 so as to receive and hold a web of pile fabric 13 (as shown in outline) in a convoluted tensioned condition. Each end frame 11 is formed by a pair of reel arms 14 which are held together at the ends by a clamping means 15. The reel arms 14 are each formed in a triangular shape and have fabric impaling hooks 16 extended from radiating sections inwardly of the reel 10. The clamping means not only envelops the ends of the reel arms 14 but also forms a socket to receive an end of the spacer bar 12 in a secure manner. The spacer bar 12 which is made of any suitable material such as wood is disposed centrally of the end frames 11 so as to be mounted on the axis of rotation of the reel 10 when the reel is mounted on a suitable frame for receiving or removal of the pile fabric.

Referring to FIG. 6, each one-piece reel am 14 is initially formed as a generally flat strip of substantially uniform width with inclined ends 17 and a central rib 18 extending longitudinally of the strip to impart strength and rigidity against transverse bending in the direction opposite to the direction of extension of the rib. The reel arm 14 includes an intermediate section 19 of uniform width and a pair of hook-containing sec tions 20, 20 spaced on either side of the intermediate section 19 between the inclined ends 17. Each section 20 contains a plurality of aligned impaling hooks 16 of conventional L- shape which are directed opposite to the hooks 16 of the other section 20; the last hook 16 adjacent the inclined ends 17 being spaced from the end of the section 20. The hook side of the reel arm 14 is formed with a rounded lip 22 between the hook-containing sections 20 while the other side of the reel arm 14 is formed with a similar rounded lip 23 (FIG. 8)

between the inclined ends 17 to eliminate burrs and to avoid exposure of any sharp edges which might cause injury.

Referring to FIGS. 4 and 6, each end section 17 is provided with a pair of apertures 24, 25, one of which is located in the rib 18 and the other of which is in the flange. A stiffener rib 26 is also formed in the arm 14 across each inclined end and hook section for a purpose as hereinafter described. The central rib 18 terminates on a sloped surface at each end so as permit overlapping of the arms 14 when bent in the end frames 11. Similarly, to provide a clearance for the overlapping stiffener rib 26, the ends of the reel arm are provided with outwardly opening slots 27 shaped to pass around a stiffener rib 26 on an overlapping reel arm. In addition, the reel arm 14 includes transverse slots 28 across the rib 18 at the lines of junction between the intermediate and hook-containing sections 20, 20 in order to provide a relief for bending of the arms 14 when subsequently bent for incorporation.

The reel arm is formed, for example, in a series of steps from a flat sheet of metal by consecutive die cuttings which cut out the desired shape and apertures. After cutting is completed the metal is subjected to a drawing step to impart the inclined ends, stiffener rib and central rib. The respective ribs 18, 26 are formed so as to have formed on a 90 angle, although other suitable angles may be used, in order to facilitate stacking of one reel arm on another as well as to ensure rigidity.

Referring to FIGS. 2, 5 and 7, the clamping means 15 includes a pair of substantially channel-shaped clamps 29 and a pair of rivets 30 which secure the clamps 29 to the end frame 11. Each clamp 29 has a pair of depending legs 31 which are provided with a pair of notches 32 sized to lie over and receive the ribs 18, 26 of the reel arms 14 (see FIG. 5). Also, a pair of holes 33 are formed in each clamp 29 between the legs 31 for permitting passage of the rivets 30. These holes 33 are made in a depressed portion of the clamp 29 which is dimensioned with respect to the remainder of the clamp to define the rearward limit of a socket defining portion 34 of the clamp. The socket defining portion 34 is provided with a pair of internal longitudinal protuberances 35 which are formed, for example, by a corresponding pair of indentations 36 in the outer surface of the clamp. In addition, the comers 37 of the socket defining portion are flared so as to provide relief areas for the corners of the spacer bar 12 should such be formed with sharp corners.

Referring to FIG. 9, in order to incorporate the flat reel am 14 into a reel, the arm 14 is bent into a generally triangular shape, the hook-containing sections 20 being bent, usually by hand, about a line passing through the slot 28 between each section 20 and the intermediate section 19 until the inclined ends 17 are substantially parallel. For example, where the reel is to be placed in a square container the hook containing sections 20 are inclinedto form an angle of about 92% which approximates the diagonals of the container. The direction of bending of the hooked sections 20 is opposite to the direction of the central rib 18 since less bending force is necessary in this direction.

Referring to FIG. 3, in order to form the end frames 11, a pair of one-piece reel arms 14 which are bent into a triangular shape as shown in FIG. 9 are overlapped at the ends so that the apertures 33 in the overlapped ends are in alignment with each other for passage of the rivets 30. In addition, the central ribs 18 of the bent arms 14 are placed in overlapping relation and the slots 27 at the ends of one reel arm are placed around the stiffener ribs 26 of the other reel arm. Thereafter, the pair of clamps 29 are placed over the overlapped ends 17 of the bent reel arms 14. The notches 32 in each clamp 29 are positioned over the respective ribs 18, 26 of the reel arms 14 while the socket-defining portions 34 are directed in the same direction as the hooks 16 on the reel arms 14. In this position, the respective spaced ribs of the overlapped reel arms impart a rigidity to the completed end frame due to the spaced points of contact. In addition, the holes 33 in the clamps 29 are aligned with the apertures 24, 25 in the reel arms 14. The rivets 30, each of which has one headed end,are then passed through the holes and apertures. The projecting end of each rivet 30 is then peened over in a conventional manner so as to fixedly secure the clamps to the reel arms.

After a pair of end frames 11 are constructed, the ends of a spacer bar 12 are inserted into the sockets formed by the clamps 29 of each end frame 11, for example, manually. In this regard, the ends of the spacer bar 12 are sized so as to fit snuggly within the clamps 29 while being held under a secure friction force under the action of the protuberances 35.

After the end frames 11 are mounted on the spacer bar 12, the reel 10 is ready for use.

It is noted that the rivets for securing the clamps of the clamping means can be replaced by any suitable securing means. For example, a threaded bolt and nut assembly can be used in place of each rivet. Further, in this instance the bolt and nut assemblies can be loosened after a pile fabric has been mounted on a reel so that, should the fabric be wound on the hooks without sufficient tension across the width of the fabric, one or both of the end frames can be pulled by suitable means in a direction away from each other to increase the tension in the fabric. After adesired tension is achieved, the bolt and nut assemblies can be retightened to hold the end frames in place on the spacer bar.

It is further noted that the clamping means can use one rivet or bolt and nut assembly instead of a pair of such devices as a single such device imparts a sufficient rigidity to the end frames to prevent skewing.

Also, the clamps of the clamping means can be shaped to define a socket defining portion of any suitable shape such as a cylindrical shape so as to receive various shaped spacer bars such as paper tubes, solid cylindrical bars and the like.

It is also noted that the reel arms can be provided with lightening holes 38 (FIG. 9) along the flattened portions of the intermediate section as well as the portion of the hook-containing sections opposite the hooks. These lightening holes permit a reduction in weight of the reel arms which are usually constructed of steel or other suitable metal without impairing the strength of the arms against bending.

The invention thus provides a reel ann which, while flat, is easily handled of itself as well as in quantity as one reel arm is nestable on another reel arm through the ribs. Also, each reel arm is easily bent into shape for forming an end frame of a reel. In addition, the flat reel arm is easily transported in quantity and, because the reel arm need not be shipped in an assembled condition on a spacer bar, a minimum of shipping space and weight is obtained. Further, of itself, the reel arm is an integral unit having the fabric-impaling hooks formed therein while being of low weight and minimum thickness. For example, the reel arm may be of a thickness of about .030 inches and of a length from about 26 inches to 78 inches although the reel arm can be of much greater lengths where needed. The hooks of such an exemplified arm with a spacing of approximately three-eighths inch can easily carry the conventionally applied weight of fabric, e.g. 5 pounds per hook.

Also, the invention provides an end frame for a reel which can be handled as a separate unit from a completed reel. In this regard, the end frames can be transported independently of the spacer bars and, thus, permit a reduction in the space required for transportation. Also, since the end frames can be readily removed from a spacer bar, the spacer bars can be easily replaced, for example, in the event that a spacer bar becomes damaged before a fabric is wound onto a formed reel of the invention.

Further, the invention provides a reel which is rigid and strong under the loadings generally imposed during handling and shipping; the strength and rigidity of the reel being imparted by the ribs and clamping means. In addition, the clamps are of a simple construction so as to be quickly and easily utilized in constructing the reel as well as in impeding movement of the end framesinto the spacer bar while allowing for movement in the opposite direction to impart greater tension in a wound fabric.

Having thus described the invention, it is not intended that it be so limited as changes may be readily made therein without departing from the scope of the invention. Accordingly, it is intended that the subject matter described above and shown in the drawings be interpreted as illustrative and not in a limiting sense.
